Khalid I. Electromagnetic compatibility of Systems of User's Radioaccess in office and campus telecommunication networks

The object - condition ЕМС in all radiofrequency, and in particular - in the not licensed ranges; The purpose - improvement of conditions ЕМС SURA, that work in the not licensed ranges of frequencies, estimation of opportunities of their steady work and development of the offers concerning escalating potential protection against handicapes; The methods - analysis of electrical circuits, radiophysics, mathematical statistics and theory of probabilities, optimum reception of signals, serial statistics, nonlinear programming, optimization, functional analysis, machine experiment and modeling; Novelty - large volume scientific and technical given about SURA, their modes, signals-handicap of conditions, configuration of the hardware and program decisions is generalized; the analysis of adaptive procedures directed on maintenance SURA is carried out; the procedure fragmentis advanced, the procedure of optimum accommodation of points of access is recommended, the mathematical model of change of working frequencies is modernized, the technique of the analysis of efficiency of use of this adaptive procedure is developed. The variant of this modernization concerning procedure of adaptation both on frequency and on capacity is offered; the adaptive procedure of spatial - temporary processing is chosen most acceptable for tasks ЕМС which is based on a method of an estimation of a spatial spectrum. The analysis and synthesis of procedures of an estimation of a spatial spectrum and adaptive indemnification of handicapes is carried out; Results - the mathematical model multifrequency of a signal and technique of the analysis of mutual modulation of a signal is developed; a technique of synthesis of procedure of optimization of accommodation of elements of communication and application her for SURA; Is introduced - The design work is skilled, which was carried out by faculty behind a task of the Ministry on extreme situations of Ukraine (№ 0101И005754); a line of results of the dissertation is placed in the textbook on telecommunications " Багатоканальний електрозв'язок.
